From the previous discussion, we can clearly see that to effectively solve the problem of particulate matter emissions from diesel vehicles, the key lies in optimizing combustion strategies, rather than simply adding DPF to National III vehicles. Although DPF can adsorb these particles, its capacity is ultimately limited. Once it reaches its adsorption limit, regeneration operation is required, otherwise it cannot continuously and effectively purify the exhaust gas.
The particulate matter emissions of National III vehicles are relatively high, which can cause the regeneration interval of DPF to become very short. Frequent regeneration operations are not only time-consuming and labor-intensive, but also accelerate the aging and failure of DPF. In addition, DPF is highly sensitive to the sulfur content of diesel and the ash content of engine oil. Using low-quality diesel and engine oil can cause the DPF to quickly lose its regeneration function and even be damaged. Considering the high price of a DPF, the installation cost appears relatively high. However, by the stage of National VI, concerns about this situation have greatly decreased. Because National VI not only involves simple DPF installation, but also encompasses many effective control strategies.
Of course, for new National VI car owners, the following aspects require special attention and maintenance in daily use:
Firstly, the external temperature can affect the regeneration time of DPF. The higher the temperature, the shorter the processing time will be. Similarly, regeneration after vehicle operation takes less time compared to regeneration when the engine is in a cold state.
Secondly, during the DPF regeneration process, the automatic exhaust or exhaust throttle valve will start working, during which some noise will be emitted, which is a completely normal phenomenon.
Furthermore, due to the combustion of particulate matter, the exhaust pipe will briefly release some smoke during regeneration, which is also a normal phenomenon.
Finally, the temperature of the engine coolant will increase during the regeneration process, so car owners need not worry too much.
